ANSYS TurboGrid Mesh and Topology Improvement

The quality of a centrifugal compressor’s mesh and its topology in ANSYS TurboGrid

Here, we explain the enhancement of the quality a centrifugal compressor’s mesh and its topology in ANSYS TurboGrid. First, we load a blade geometry into ANSYS TurboGrid. you should prepare it using a CAD software such as ANSYS BladeModeler or DesignModeler. Second, we generate an initial mesh by the default meshing settings. We can change the visibility of mesh components. For instance, we can make blade, splitter, tip and hub visible. Now we can modify the mesh. we can change expansion. Higher expansion rate results in coarser mesh and by changing this factor we can optimize the boundary layer mesh. Tip mesh and trailing edge

Second, we generate an initial mesh by the default meshing settings. We can change the visibility of mesh components. For instance, we can make blade, splitter, tip and hub visible. Now we can modify the mesh. we can change expansion. In addition, higher expansion rate results in coarser mesh and by changing this factor we can optimize the boundary layer mesh. Tip mesh and trailing edge mesh, has been improved in the new versions of ANSYS TurboGrid. At the cutoff edge, a higher mesh density is often required to see the details of flow. Cutoff edge split factor controls the mesh density in this area. Now we can use the improved mesh in CFD simulations to make accurate predictions about the centrifugal geometry.
